LAP-STAND.

Specification of Letters Patent.

Patented June 22, 1915.

To all whom it may concern 7 Be it known that I, HIRAM D. TURNER, acitizen of the United States, residing at Manchester, county ofHillsboro, State of New Hampshire, have invented an Improvement inLap-Stands, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawingrepresenting like parts.

This invention relates to improvements in lap stands for cardingmachines and is designed with a view to facilitating the introduction ofthe roll of lap into its supporting guides at the admission end of thecarding machine and also to facilitate the piecing of the end of a newlap upon the end delivered from an exhausted roll.

In the usual form of carding machines the rod which forms the axle ofthe roll of lap is inserted in slots in brackets extending'upwardly fromthe admission end of 7 the carding frame and thelappermitted to restupon a driven lap roll whereby it is delivered over the feed plate tothe feed roll and thence'by the licker-inmechanism in the usual manner.The end brackets usually are provided with posts having supplementalbrackets having journals adapt ed to receive the axle of a spare lapwhich is retained therein until the active roll of lap is exhausted,whereupon the attendants lift the lap from the last mentioned bracketsand drop it into active position upon the lap roll.

In order to position the end of the new lap so that it may properly bematted with the end of the preceding lap which is being fed into thecarding machine it is frequently necessary to turn the lap which isbeing introduced forward or backward so that the ends of the laps may beunited without forming a ridgeor a thin place in the web which is beingfed to the carding machine.

One of the objects of the present invention is to provide means forsupporting a spare lap in such position thatit may be transferred easilyinto active position without the necessity of touching'the material uponthe lap thereby avoiding injury to the same. a

Another object of the invention is to provide means for. rotatablysupporting the lap which is being introduced a suflicient distance aboveits active position to afford accessto the edge of the new lap and topermit it to be placed properly relative to the end of the nextpreceding lap.

Other objects of the invention and the nature thereof will more fullyappear from the following description and the accompanying drawings andwill be pointed out in the annexed claims.

In the drawings: Figure 1 represents the admission end of the usualcarding machine with the improved lap support applied thereto, Fig. 2 isan end view of the same centrally broken away.

As illustrated in the drawing herein the admission end 1 of the usualcarding machine frame is provided with a bracket 2 having a verticalslot 3 in which the rod or axle a of the active roll of lap 5 is adaptedto rotate, the lap being supported upon a lap roll 6 and being deliveredtherefrom is further advanced by a feed roll 7 to the licker-in andthence to the cylinder.

It is to be understood of course that each side frame of the machine isprovided with similar brackets and that the lap stand hereinafter to bedescribed comprises duplicate or complementary parts arranged upon saidend frames so both ends of the lap will be simultaneously supported andmoved.

The brackets 2 are provided adjacent their upper endsand upon thesidesof the slots toward the carding machine with bosses 8 having verticalapertures to receive and support vertical standards 9 upon which meansare mounted for supporting a spare lap.

The preferred means illustrated herein com to cause the handles 14 tomove in unison and also provides means for supporting the spare lap inelevated position as will hereinafter appear.

The ends of the arm 5 are desirably bifurcated, oneof the fingers ofsaid bifurcation 18 being curved into hooked form adapted to receive therod or axle 4 of the lap while the other finger 19 is extended at anangle to the axis of the portion 5 of said lever to provide a guidingmeans for directing the axle 4 into the slot 3 in a manner hereinafterto be described.

The axis of the extension 5 is disposed at such an angle to the axis ofthe handle member 14 that when the latter is in depressed position theaxle of the lap which rests in the bifurcation of said lever will be onthe saine side of the vertical axis of the standard 9 as the rod or stopwhich connects the levers or handle portions v14 whereby said rod orstop will be pressed against the sides of the standards 9 to support thespare roll in elevated position.

When the material upon the active lap has become exhausted the emptyaxle is re moved from the vertical slot 3 to permit the introduction ofthe spare lap. The handle 14: is thereupon raised and the spare lapcarried about the pivotal support 13 until the member assumes thedepending position shown in dotted lines in Fig. 1 at which time theaxle of the roll is supported by the hooked finger 18. WVhen in thisposition the lap is free tovbe rotated in such a manner that the endthereof may be wound or unwound and easily pieced to the preceding lap.

When the laps, have been pieced the bandlelt is thrown still fartherover to the 7 left beyond the position shown in Fig. 1,

whereby the ends of the, axle of the lap will be caused to contact withthe side of the standard Sadjacent to and above the slot 3 forcing saidaxle out of its engagement with the hooked members 18 and permitting thelap to drop into active position the axle of the "roll being guided andsteadied in its descent by the inclined finger 19.

It will be observed that the mechanism a above described provides aconvenient means for supporting the spare lap and transferring the sameinto active position in the carding machine.

It is to be understood that the mechanism described herein is one of thepreferred forms of my invention but that this invention contemplatesbroadly means for supporting a lap "or like device in proximity to itsactive position, and means for moving thesame thereover into activeposition in com risin means for su ortin a la in active position,pivotally mounted means for supporting a spare lap conveniently nearsaid; active positionand adapted upon rotation to position said sparelap in the vertical plane of the active position but reactive position,adjustable means rotatably.

mounted abovesaid position for supporting a spare lap above said activeposition and for swinging the same adjacent to but sufiiciently removedfrom said active position to perinitthe end of the lap thereon. to beconveniently pieced to the next preceding lap.

1. In an apparatus of the class described com risin means for su ortinthe la in active position, pivotallymounted meansfor supporting a sparelap above said active po- SltlOIlflIldfor swinging the same ad acent tobut sufliciently removed from said active positionto permit the; end ofthe lap to be conveniently pieced to the next preceding lap and meansfor transferring said roll to active position.

5. In, an apparatus comprising a. frame having slots to receive the endsof the axle of a roll of lap and to maintain the same in activeposition,supporting standards adjacentto said slots, a pair of angularlevers pivotally mounted at their elbows on said standards eachhaving atone end a hooked member to engage and support the axle of the lap and atthe opposite end a handle, a stop carried thereby adapted to engage theside of the standard whereby the axle of the lap when in raised positionwill be on the same side of the pivotal support as said stop.

6. A lap stand comprising a frame having of the class described slots toreceivezthe ends of an axle of a roll of lap, standards supported bysaid frames, members pivotally mounted upon said stands and having meansadapted to engage and support the axle of a roll of lap, handlesextending from said members at an angle to the axial plane and meanscarried by said handles adapted toengage said standards to supportsaidlap in raised position.
